What must the system do?
Define the engineering objective and the condition that must be understood.
Engineering Projects
Build the system.Test the engineering.
Projects connect principles, components, calculations, and evidence around a working objective. This hub organizes the existing Mechatrovich project material by what is being built and tested.
INTRODUCTION
One project. Three connected responsibilities.
Define the objective and system boundary, assemble the sensing, actuation, control, or design elements, then compare the result with the intended behavior. The projects below use only existing Mechatrovich material.
01 / CONTROL
Control & Automation Projects
Close the loop around a physical process using measurement, controller logic, and actuation.
02 / SENSOR
Sensor & Experimental Projects
Connect the sensing or transduction principle to observable system behavior and operating limits.
EXPERIMENTAL BUILD
Ultrasonic Mist Generation
Piezoelectric drive, atomization, water depth, droplet behavior, and dry-running protection.
Open the experimental build →SENSOR FOUNDATIONHumidity Sensing for Feedback
Placement, response time, calibration, condensation, and control use.
Read the sensor foundation →SYSTEM CONTEXTAeroponic Systems
Root-zone delivery, humidity, nutrients, pH, EC, reservoir behavior, and failure modes.
Understand the process →03 / DESIGN
Design Projects
Turn a dimensioned requirement into a structured model and verify the result against the intended geometry.
DESIGN PROJECT 01
Siemens NX Sketch-to-Part Exercise
Dimensioned exercise drawing, finished model, progressive hints, feature sequence, and downloadable sheet.
Start the design project →DESIGN WORKFLOWSketch to Production Drawing
Connect constrained sketches, part features, assemblies, and drafting.
Read the NX workflow →Engineering workflow
Define → Build → Test
Keep the objective, system boundary, implementation, and evidence connected throughout the project.
→
How do the parts connect?
Connect the physical components, calculations, and implementation choices.
→
What does the evidence show?
Compare the observed result with the intended behavior and decide what follows.
Keep the sequence visible. The objective, implementation, and observed evidence should remain connected. A result without its system context is easy to misinterpret.

Frequently asked questions
Keep the engineering context visible.
Use the questions below to choose the correct existing guide, tool, or project.
What counts as a Mechatrovich engineering project?
A project connects several engineering elements around a working objective and shows the system boundary, implementation decisions, or observed result.
Which project should I start with?
Use the controlled aeroponic-system design for a full system view, PI humidity control for closed-loop evidence, or NX Practice Exercise 01 for a focused CAD task.
Are the sensor and control projects connected?
Yes. The aeroponic material connects humidity sensing, ultrasonic mist generation, fan actuation, PWM, and PI control.
Is there a downloadable CAD project?
Yes. NX Practice Exercise 01 includes a downloadable exercise sheet alongside the browser guide, progressive hints, and self-check.
Which tools support the projects?
The current site provides the Engineering Unit Converter, CSV Measurement Inspector, and the quality-engineering calculation and analysis tools.
